WILLIAM NEASI-IAM, OF NEW YORK, N. Y.

PRINTING-PLATE HOLDER.

Application filed October 21, 1908.

T 0 all whom it may concern:

Be it known that 1, WILLIAM NEASHAM, a citizen of the United States, residing at the borough of Manhattan, New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Printing-Plate Holders, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in printing plate holders and is particularly adapted for use in the printing arts where various printing plates of different sizes may be successively bound to the same bed plate and quickly adjusted into position with precision.

In the accompanying drawings Figure 1 is a plan view illustrating an application of my invention. Fig. 2 is a side view of the same looking from right to left. Fig. 3 is a cross section of one of the clamping attachments showing the position of the screw and Fig. 4 is a cross section of another screw provided with a suitable collar.

5 is a base of wood or other suitable material upon which the metallic bed plate is suitably fastened. Said plate is preferably marked with lines crossing at right angles and running longitudinally and transversely along the face of the same to assist adjustment.

7 are holes penetrating the plate 6 suitably tapped to receive the binding screws 8 to be hereinafter referred to.

9 are the clamping attachments provided with beveled sides 10 adapted to engage the beveled side of the printing plate 11. This printing plate is placed upon the bed plate 6 and adjusted thereon, after which the clamping attachments 9 provided with elongated slots 12 are placed against the side of the same so that the beveled sides come together. These elongated slots are preferably provided with a suitable bevel milled to engage the beveled under surface of the milled collar 13 so that after the printing plate has been properly adjusted upon the bed plate and the binding members 9 have been placed in position to hold the same, the binding screws 8 Specification of Letters Patent.

may be driven home firmly holding the combination in position for use. Collars such as 13 suitably milled upon the exterior surface are slipped over the screws in the same manner as a washer so that as the screw is driven home the milling upon the under surface of the collar 13 engages the milling upon the beveled face of the elongated slot 12 firmly clamping the combination together.

From the arrangement disclosed it will be readily understood that successive plates of various sizes can be rapidly clamped in position upon the bed plate with accurate adj ustment. It will be observed that the same bed plate may be used for mounting various sized printing plates owing to the disposition of the various holes and the method of shifting and clamping the various members together.

\Vhile the invention has been illustrated and described as particularly adapted for use in holding printing plates in position, it will also be readily understood that the invention is adapted for holding any article in a given position where the same is of such a nature as to permit of the use of means similar to those above set forth.

Various modifications may be made without departing from the spirit of the invention.

Having described my invention, what I claim as new, and desire to secure by Letters Patent is:

In a printing plate holder, a base provided with threaded holes, clamps provided with elongated slots adapted to hold a printing plate in position upon said base, said elongated slots provided with milled beveled sur faces, milled collars adapted to engage said milled beveled surfaces and screws adapted to be inserted through said milled collars and elongated openings and into said base to clamp said plate in position upon said base.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM NEASHAM.
